Function of genomic regions bound by TFs in vivo [Biochemistry]

Function of genomic regions bound by TFs in vivo [Biochemistry]: In animals, each sequence-specific transcription factor typically binds to thousands of genomic regions in vivo. Our previous studies of 20 transcription factors show that most genomic regions bound at high levels in Drosophila blastoderm embryos are known or probable functional targets, but genomic regions occupied only at low levels have...
